Suppose 10 atoms of carbon (C) react with 20 atoms of oxygen (O). According to the Law of Conservation of Matter, how many atoms will there be in the product of this reaction?(1 point)

30
15
10
20

30

To find the number of atoms in the product of this reaction, we need to calculate the total number of atoms in the reactants and then determine if any atoms are left over or if any new atoms are formed.

The reactants in this reaction are 10 atoms of carbon (C) and 20 atoms of oxygen (O).

To calculate the total number of atoms in the reactants, you can simply add the number of atoms for carbon and oxygen:

10 atoms of carbon (C) + 20 atoms of oxygen (O) = 30 atoms in total

Therefore, according to the Law of Conservation of Matter, there would be a total of 30 atoms in the product of this reaction.

So, the correct answer is 30.
